CLUTCH.

SPECIFICATION forming part of Letters Patent No. 747,298, dated December15, 19031.

Application filed July 29,1901. Renewed May 5, 1903:. Serial No.155,788. (No model.)

To aZZ whom it may concern:

Be it known that I, TIMOTHY CARROLL, a citizen of the United States,residing at Anaheim, in the county of Orange and State of California,have invented a new and useful Improvement. in Clutches, of which thefollowing is a specification.

The object of this invention is to provide a simple and strong clutchdevice for connecting and disconnecting a revolving spool to rotate withand to be free from rotation with a rotary shaft.

One object of my invention is to provide means whereby a large number ofwindingspools may be arranged on a single shaft and said spools bereadily connected and disconnected to rotate with and to be free fromrotating with the rotary shaft.

Another object of this invention is to provide means whereby one or moresets of integral clutch members and theirretaining devices may bemounted on a shaft from either end without the use of split or two-partelements.

With this and other objects in view the invention consists in thespecific construction of the clutch members and in the means formounting them on a shaft in sets in such manner that one member isrotatable and the other is longitudinally movable, but isnonrotatable.

The accompanying drawings illustrate my invention.

Figure I is a side elevation of a windlass embodying my invention.Portions of the shaft and the means for rotating the shaft are omittedin order to contract the view. Fig. II is an axial section on line IIII, Fig. I. Fig. III is a cross-section on line III III, Figs. I and II,looking in the direction of the arrow. Fig. IV is a cross-section online IV 1V, Figs. I and II, looking in the direction of the arrow.

1 indicates a rotary shaft furnished with a splineway 2. In practice anydesired number of splineways may be provided. In the drawings twosplineways are shown.

3 indicates a spool journaled on the shaft and furnished withasocket 4,opening toward the splineway.

5 indicates a collar fixed on the shaft inside the socket to engage thebottom 6 of the socket to prevent the spool from moving endwise towardthe splineway.

7 indicates a collar fixed on the shaft to engage the end of the spoolopposite the socket to prevent endwise movement of the spool away fromthe splineway.

8 indicates a sliding member mounted on the shaft furnished with aprojection 9 to seat in the socket 4 to prevent relative rotationbetween the socketed member or spool 3 and the sliding member 8. Saidsliding member is also furnished with a lateral opening 10,communicating with the splineway 2.

11 indicates a spline in said lateral opening extending into thesplineway 10, and 12 indicates means for fastening the spline in saidopening. Such means consist in a screw which is screwed into a socket13, formed in part in the spline 11 and in part in the wall of theopening 10, in which said spline is inserted. The spool is furnishedwith a lateral opening 14, communicating with the socket 4' at the innerend thereof.

15 indicates a screw inserted through the collar 5 and screwed into theshaft to hold the collar in place.

The cross-section of the socket 4 and of the male member or projection 9of the clutch is such as to prevent rotation of the spool and thesliding member relative to each other when the male member or projection9 is inserted into the socket 4. Preferably the crosssection of suchprojection 9 and socket 4 is square or otherwise angular.

In order to provide for utilizing the spool to its fullest extent, theportion a of the spool which extends around the socket 4. will have anexternal cylindrical form to serve as a winding member upon which a ropeor other flexible connection can be readily applied;

The sliding member 8 is also constructed to form a cylinder for windinga flexible connection. 16 indicates flanges at the ends of into thesocket 4zand brought to the appropriate place and fastened with thescrew 15, turned by means of a screw-driver inserted through the lateralhole 14. Then to connect or disconnect the spool and the rotary shaftthe sliding member 8 will be slid by hand or by any suitable means (notshown) which the constructor may provide therefor to bring its malemember 9 into and out of the socket 4.

In assembling the clutch members and the rings on the shaft if themember 3 be placed in the shaft spool end first, as from the righthandend of the shaft in the drawings, and it be impossible to move it beyondthe point where it is to be secured, as when it abuts against a bearingor a set of clutches already in place, it will be seen that the only waythat the ring 5 can be secured in position is by means of the opening14, which is located virtually at the bottom of the axial recess of themember and through which the screw-driver must be inserted fortightening the screw or for loosening it for removing the ring and theclutch member.

In practice any number of spools may be applied on a single shaft, andsaid shaft is to be provided with splineways for the sliding members,respectively, for the spools and also with screw-threaded sockets forthe screws which fasten the collars in place. The collar 5 serves toposition the spool, but does not interfere with the operation of thesliding member 8.

By providing the shaft 1 and the member 3, constructed to slide alongand to rotate on said shaft-,the collars 5 and 7,arranged to slide alongsaid shaft, and means 15 and 17 to fix said collars to said shaft tohold said member 3 against endwise movement it becomes possible to applythe spool at any appropriate point on said cylindrical shaft of uniformdiameter.- By providing the member 8, constructed to slide along theshaft, and means comprising the splineway 2, the spline 11, and thescrew 12, to hold said member against rotation and to allow it to slidealong the shaft a plurality of members of this kind may be assembled onthe shaft at the appropriate places and used as one of the clutchmembers witha minimum amount of cutting away of the shaft and of themember to accomplish the purposes above stated.

By arranging the collars 5 so that they slide along the shaft theconvenience of assembling the clutch from the side toward which thesocket opens is increased, for the reason that after the member 3 hasbeen brought to its position from the right the ring 5 may be What Iclaim, and desire to secure by Letters Patent of the United States, is-

1. The combination, with a rotatable shaft, furnished with a splineway,of twolongitudinally-perforated clutch members mounted on said shaft,one of said members being perforated radially and provided with a flangeat each end and an axially-arranged projection at one end, saidprojection being angular in cross-section; a spline removably secured insaid perforation with its inner end in the splineway; the other clutchmember being provided with flanges and having one end of its perforationenlarged and angularin cross-section to receive the projection of theother member; and means for holding said last-mentioned member againstlongitudinal movement on the shaft.

2. The combination of a rotary shaft furnished with a splineway; a spooljournaled on the shaft and furnished witha socket opening toward thesplineway, and also furnished with a lateral opening communicating withthe socket at the inner end thereof; a collar fixed on the shaft toengage the end of the spool opposite the socket to prevent endwisemovement of the spool away from the splineway; a collar inside thesocket to engage the bottom of the socket; a screw inserted th rough thecollar and screwed into the shaft; a sliding member mounted on the shaftand furnished with a projection to seat in the socket to preventrelative rotation between the spool and the sliding member, said slidingmember being also furnished with a lateral opening;

asplinein said lateral opening extending into the splineway; and meansfor fastening the spline in said opening. a

3. A clutch comprising two flanged and longitudinally-perforatedmembers, the perfora- IGO tion of one of said members being enlargedname to this specification, in the presence of two subscribingwitnesses, at Los Angeles, California, this 20th day of July, 1901.
